Curtis Johnstone

My name is Curtis Johnstone – I am the creator and chief contributor to Inside OCS.  I am currently an architect and unified communications domain expert working at Quest Software. My background is rooted in Microsoft Exchange application development, but I have now focused and worked extensively with OCS for over 3 years now. I have architected and lead several OCS and OCS R2 rollout’s with lots of hands-on experience with everything from architecting, deployment, management, developing custom solutions, and troubleshooting.

This blog is intended to share my experiences and knowledge to help IT managers, Administrators, and End-Users using Microsoft Office Communications Server, Office Communicator, and Office Live Meeting.

Enjoy, Curtis

  • An update Sam,

    The November 2010 OCS 2007 R2 Cumulative Update (KB 2291453) introduced hotfix 2415902 which was aimed to address this, so sometimes in your contact list you see the following after the availability status:
    – No IM
    – IM Only
    – No Voice

    These are set mostly by the nature of the device you are connecting with. For example, if a user connects with a IP Phone that does not support Instant Messaging, you might see the “No IM” after their availability.

    Microsoft is in the process of updating their documentation around this.
